Description

Automatic card flipping mechanism

The present invention relates to an automatic card flipping mechanism, in particular, a card flipping plate with a playing card is driven to flip, and at the same time another card receiving plate is flipped to receive the playing card. After the card flipping plate and the card receiving plate are restored to their initial flat state, the playing card can be flipped over so that the top and bottom surfaces are interchanged, thereby achieving the correction of incorrect card faces without manual intervention.

According to the current electronic poker game machine, the game is fully automated. It uses an automatic shuffler to automatically shuffle the cards, and uses the suction cup of the machine arm to take cards from the automatic shuffler. The machine arm then moves the sucked poker cards to the camera identifier to identify the numbers or patterns. After the electronic poker game machine reads the number or pattern information, the cards are dealt to each player. Therefore, it can completely avoid human intervention and achieve the effect of fairness and equity of the game. However, if there are uneven poker cards that are stuck during the automatic shuffling, the corners may be accidentally turned over to an incorrect card face (i.e. the points and suit on the front of the card face up, and the back of the card face down), causing the camera identifier to be unable to identify the poker card after the robot arm absorbs it. At this time, the poker card needs to be manually turned over to make it face up for identification, otherwise the electronic poker game cannot continue; however, manual intervention is required to solve unexpected situations during the electronic game, which may lead to the following problems:

1. Game fairness issues: If manual intervention is required to flip the poker cards, this may cause players to question the fairness of the game. Players may believe that manual intervention can interfere with the game results and may cause players to distrust the game, thereby affecting the reputation of the operator.

2. Manual operation cost: If manual intervention is required to flip the poker cards, then corresponding human resources are needed to supervise and perform this task, which will increase operating costs and thus affect operating income.

The end of the push plate arm 273 faces the through hole 22 under the card, and the end of the push plate arm 283 faces the through hole 23 under the plate. The pivotal position height of the first connecting rod 17 and the card handle driving arm 272 is higher than the card handle fulcrum shaft 271, and the pivotal position height of the second connecting rod 18 and the plate handle driving arm 282 is lower than the plate handle fulcrum shaft 281, so that the push plate arm 273 pivots to protrude from the card placement slot 21 through the through hole 22 under the card, and the push plate arm 283 pivots to protrude from the flip plate through the through hole 23 under the plate. 20; and a card receiving tray 30, one side of which is provided with a pivot assembly on the disk shaft portion 301 of the shaft seat 202, the plate shaft portion 201 and the axial extension line of the disk shaft portion 301 are non-parallel to form an angle θ, and the card receiving tray 30 is provided with a positioning convex plate 302 corresponding to the stop convex plate 203 on one side of the disk shaft portion 301, and the card receiving tray 30 is pivotally engaged with the card placement slot 21, so that the positioning convex plate 302 abuts against the stop convex plate 203, so that the card receiving tray 30 is pivotally positioned at a set angle; by In the above mechanism, the incorrect poker card 1 is placed in the card slot 21, and the turntable 14 drives the flip plate 20 to flip upward and simultaneously links the card pusher handle 27 and the plate pusher handle 28 to pivot, so that the card pusher arm 273 can push the poker card 1, and the plate pusher arm 283 can push the receiving plate 30 to flip upward, so that the poker card 1 is pushed into the receiving plate 30, so that the receiving plate 30 is restored to a flat position, and the top and bottom positions of the poker card 1 therein are exchanged, so as to achieve the effect of automatically flipping the card face and correcting the incorrect card face.

The composition, function and effect of the present invention are described in detail as follows: As shown in Figures 1 to 7, the frame 11 of the automatic card flipping mechanism 10 can be fixed integrally on the countertop of the electronic game machine to facilitate the placement and retrieval of cards by a machine arm or other automatic card taking mechanism, and the automatic card flipping mechanism 10 is electrically connected to the electronic game machine to control the operation of the automatic card flipping mechanism 10 to facilitate automated operations. The card slot 21 of the present invention is located on the outer side of the flip plate 20 which is farther from the plate axis 201 relative to the receiving plate 30, and the axial extension lines of the plate axis 201 and the plate axis 301 intersect at a non-parallel angle θ. When the flip plate 20 is turned upward, the card slot 21 and the receiving plate 30 are inclined obliquely, and the receiving plate 30 is turned upward at an oblique angle at the same time (as shown in Figures 6 and 7). In this way, when the poker card 1 in the card slot 21 is aligned with the receiving plate 30, the poker card 1 is pushed toward the receiving plate at an oblique angle by the card pushing arm 273. 30, the airflow between the poker cards 1 and the receiving tray 30 can be discharged smoothly from the opening direction to reduce the wind resistance, thereby making the poker cards 1 fall into the receiving tray 30 at an oblique angle, avoiding the poker cards 1 directly resisting the wind resistance due to the front angle flipping, so that the air between the poker cards 1 in the card slot 21 and the receiving tray 30 directly and instantly collides to generate turbulence. In addition to the large wind resistance making the motor 15 that drives the flip plate 20 to flip heavier, the turbulence will also cause the poker cards 1 to fly randomly without direction, so that the poker cards 1 may fall outside the receiving tray 30.

When the electronic poker game is being played and a poker card 1 is flipped incorrectly, the electronic poker game uses a robot arm or other automatic card taking mechanism to place the poker card 1 on the card placement slot 21 of the automatic card flipping mechanism 10. Initially, the proximity switch 16 corresponds to the outer protrusion 141 that rotates with the turntable 14 (as shown in FIG. 4). At this time, the shaft pin 142 on the turntable 14 pulls the connecting rod 26 down to the bottom dead center, so that the flip plate 20 and the card receiving plate 30 are in a horizontal state; then, the motor 15 drives the turntable 14 to rotate (in this embodiment, it rotates counterclockwise, but not limited to this), so that the outer protrusion 141 leaves the position of the proximity switch 16 (as shown in FIG. 4). As shown in FIG. 5, at this time, the proximity switch 16 senses the information that the turntable 14 starts to rotate. When the turntable 14 rotates about half a circle, the shaft pin 142 pushes the connecting rod 26 up to the top dead center. The flip plate 20 uses the plate shaft 201 as the rotation axis, and the distance between the plate shaft 201 and the connecting seat 24 as the lever arm, so that the connecting rod 26 pushes the flip board 20 upward to a certain angle, and the push handle 27 and the push plate handle 28 are lifted upward along with the flip board. At this time, because one end of the first connecting rod 17 and the second connecting rod 18 are respectively hinged on the cross plate 12, the first connecting rod 17 with a fixed length generates a pulling force on the handle driving arm 272 on the side of the handle fulcrum shaft 271. Since the pivot point of the first connecting rod 17 is higher than the pivot axis 271 of the card handle, the card pusher handle 27 rotates clockwise, and the card pusher arm 273 is driven to protrude from the bottom surface of the flip plate 20 through the through hole 22 under the card and out of the card slot 21, and push the playing card 1; at the same time, the second connecting rod 18 of fixed length moves toward the plate. The handle driving arm 282 generates a pulling force on the side of the handle pivot shaft 281. Since the pivot position height of the second connecting rod 18 is lower than the handle pivot shaft 281, the push handle 28 is rotated counterclockwise, and the push arm 283 is driven to protrude from the bottom surface of the flip plate 20 through the bottom through hole 23 of the plate, and push the flip plate 20. The receiving plate 30 is rotated with the plate shaft 301 as the rotation axis, so that the receiving plate 30 pivots at an upward angle to face the card slot 21, so as to receive the playing card 1; at the moment when the flip plate 20 flips, the playing card 1 is affected by the centrifugal force and has the force to be thrown outwards. At this time, the guiding slope 211 uses the surface slope to limit the playing card 1. The playing cards 1 are not thrown out, and at the same time, the playing cards 1 are pressed against the receiving plate 30 to ensure stable reception; and when the side baffle 212 is located at an upward angle of the flip plate 20, the card placement slot 21 is adjacent to the lower side of the guiding slope 211, and when the card placement slot 21 is turned over to an inclined angle, the playing cards 1 are prevented from sliding out from the bottom side. Furthermore, when the receiving tray 30 is pushed by the tray pusher arm 283 and pivots upward to a set angle, the positioning protrusion 302 that rotates with the receiving tray 30 will contact the stop protrusion 203, so that the receiving tray 30 stops pivoting, thereby limiting the receiving tray 30 to receive the poker card 1 at a fixed angle.

Then, the motor 15 drives the turntable 14 to continue rotating. The turntable 14 rotates about half a circle, and the shaft pin 142 pulls the connecting rod 26 back to the bottom dead center, so that the outer protrusion 141 returns to the position corresponding to the proximity switch 16. At this time, the proximity switch 16 senses that the turntable 14 has rotated one circle, and stops the motor 15 from driving the turntable 14. During this process, the flip plate 20 is pulled down with the plate shaft 201 as the rotation axis to be in a horizontal state, and the push handle 27 and the push plate handle 28 fall down together with the flip plate 20. At this time, the first connecting rod 17 causes the handle drive arm 272 to generate a reverse thrust. Then the push handle 27 rotates counterclockwise, and the push arm 273 is retracted to the bottom of the flip board 20; at the same time, the second connecting rod 18 causes the plate handle driving arm 282 to generate a reverse thrust, and then the push handle 28 rotates clockwise, and the push arm 283 is retracted to the bottom of the flip board 20, so that the receiving plate 30 returns to the flat state of the flip board 20 with the plate shaft 301 as the rotation axis, and returns to the initial state; in this way, the top position of the poker card 1 originally in the card slot 21 is converted to the bottom position in the receiving plate 30, achieving the effect of automatically correcting the incorrect card surface without manual intervention.

The above-mentioned embodiments are only preferred embodiments for fully illustrating the present invention, and are not intended to limit the features of the present invention. Any re-creation using the relevant technical means and creation principles of the present invention still falls within the scope of the equivalent structural creativity of the present invention.
